MichelinA1 Airstop Tube(Return to Product Page)

purchased two and both had flats in first 10 days

Great training tube, I' ve had no problems and less than normal flats running this through the summer

This tube last well and have never had a leak at the stem. Worth the money!

This is a very good quality product

This is simply a great tube because of the smooth,threadless valve that comes in many sizes. Good for frame - fit hand pumps. Won't destroy the gasket in the chuck. Light and supple.

Good all around road tube for most everything I do for long training rides.

always my prefered ones. relaible and easy toadjust to the pumps

I like 'em. Obviously a quality product. Can't go wrong choosing these.

Nice weight tube with good valve at a very competitive price

I've been using these now for about 3 years and have had good luck with them. Whenever I do get a flat they are easy to change & the 40mm valve stem is perfect for my wheels.

my basic road tube, light, flexible pretty good life. smooth stem great on pumps.

a great choice for everyday riding that helps with flat resistance, and can run about a week without having to pump it up. Slightly heavier than racing clincher tubes, but the increase in reliability and reduced maintenance is a plus.

By far the best tubes I have ever purchased, bought 5 but have not had a flat yet, with lesser tubes, one flat a week. will never buy a cheap tube again!

These are solid, reliable tubes with a nice smooth valve. The key is the solid a reliable part. Bargain tubes tend to fail at the valve stem - a leak that cannot be fixed. I have not had this sort of problem with Michellin A1 Airstops.

I use these because they are one of the only tubes that does not have threads on the outside of the valve. There are a few threads on the end but not so that your pump gets hung on them. I have had a problem with all my pumps grabbing the threads on the valve making it hard to remove the pump and a few times tearing the valve off the tube. I never have this problem and I have no idea why the other tubes have threads. It is a ridiculous waste of time and manufacturing to do this, yet it seems the companies are oblivious to it. like Michelin tires and I use them on my bike. Usually the Pro Race 3 I want to try the Pro Race 4. Currently I am using a tougher tire by Michelin that cost less but has worn very well. I used to use Michelin on my car when it was more expensive than my bike. I had a Jag X type.

I decided to change to this tube so that I wouldn't need to pump up my tires every week or so to hold 110-120 pounds pressure. These have been installed for about a month now, and the pressure is holding. So... it is doing what I wanted, and the ride is comfortable, and no flats so far. Excellent tube!

What can I say? They hold air, don't weight too much, are pre-powdered and don't cost much. I like the smooth presta stem that doesn't chew up the rubber on my pump.

Nice basic tube. I like the smooth valve as it does not tear up my silca pump head gasket.

I've used these tubes for years for all-around training and fast touring. (I use Continental Grand Prix 4000 tires.) I love the durability that comes with the few extra grams - I've literally ridden entire seasons without a flat! I also love the smooth stems (longer stem available for deep rims). The non-threaded stem design means your pump gets a good seal with no air leak, and it's easy to slip the pump head on and off.

I put these tubes in with new Vredestein Tri Comps each year - great reliable combination for 2000 plus miles year
